【摘要】：進入二十一世紀,電子、移動通訊、互聯(lián)網等領域發(fā)展迅猛,催生出各式各樣的電子產品,如智能手機、平板電腦、穿戴式設備。電子產品更新?lián)Q代快,而目前大多數中小型電子企業(yè)仍采用人工測試,效率低、差錯率高,嚴重阻礙產品質量的提升。也有一些企業(yè)使用專門定制的測試系統(tǒng),但這些測試系統(tǒng)在通用性、靈活性等方面難以令人滿意。因此,設計適用于中小型企業(yè)的通用自動測試系統(tǒng)對提高產品測試質量、縮短產品上市時間以及擴大公司規(guī)模都有不可或缺的作用。本文分析了自動測試系統(tǒng)的發(fā)展趨勢,采納了現(xiàn)有一些測試系統(tǒng)的優(yōu)點,綜合考慮系統(tǒng)的通用性、可擴展性、易操作性、可配置性等因素[1],采用NI公司Test Stand和Lab VIEW作為上位機軟件開發(fā)軟件,結合嵌入式測試設備,基于模塊化設計理念,構建了通用自動測試系統(tǒng)。該系統(tǒng)通過NI采集卡實現(xiàn)了電子產品的電壓、電流、電阻、頻率等電氣信號的測量;測控模塊與上位機分別作為TCP客戶端與TCP并發(fā)服務器實現(xiàn)多產品多種常用通信端口(如UART、SPI、I2C、USB等)的傳輸性能的并行測試,在測控模塊上建立了簡易的HTTP服務器,使得上位機能夠通過瀏覽器可視化配置測控模塊整體參數。此外,本系統(tǒng)能夠通過參數配置表集中配置測試參數,同時具備權限管理、測試流程控制、數據分析、故障警報、報表生成等功能。對于不同的產品,傳統(tǒng)自動測試系統(tǒng)采取的策略是“軟件重新設計”,與其相對比,本自動測試系統(tǒng)采取的策略是“測試單元組合成測試項目組,測試項目組與測試條件相應的程序模塊構成測試序列,不同的產品使用不同的測試序列集”,使得系統(tǒng)通用性與擴展性大大增強。而且,測試項目、流程、參數可以簡單靈活配置、快速部署,可滿足產品快速更新?lián)Q代帶來的測試需求。
[Abstract]:In the 21 century, electronics, mobile communications, the Internet and other fields have developed rapidly, resulting in a variety of electronic products, such as smartphones, tablets, wearable devices.At present, most small and medium-sized electronic enterprises still use manual testing, which has low efficiency and high error rate, which seriously hinders the improvement of product quality.Some enterprises also use customized test systems, but these test systems are not satisfactory in generality, flexibility and so on.Therefore, the design of a general automatic test system for small and medium-sized enterprises plays an indispensable role in improving the quality of product testing, shortening the time to market and expanding the size of the company.This paper analyzes the development trend of the automatic test system, adopts the advantages of some existing test systems, and considers the universality, expansibility and easy operation of the system.In this paper, Test Stand and Lab VIEW of NI Company are adopted as the software development software of upper computer, combined with embedded testing equipment, and based on the idea of modular design, a general automatic test system is constructed.The system realizes the measurement of electrical signals such as voltage, current, resistance, frequency and so on through NI acquisition card.The measurement and control module and the host computer are used as the TCP client and the TCP concurrent server respectively to realize the parallel test of the transmission performance of many kinds of common communication ports (such as UARTN SPI I 2CU USB etc.). A simple HTTP server is established on the measure and control module.So that the host computer can visually configure the overall parameters of the measurement and control module through the browser.In addition, the system can configure test parameters through parameter configuration table, and has functions of authority management, test flow control, data analysis, fault alarm, report generation and so on.For different products, the traditional automatic test system adopts the strategy of "software redesign". In contrast, the strategy adopted in this automatic test system is "the test unit is combined into a test project group,"The test group and the test condition corresponding program module constitute the test sequence, different products use different test sequence set ", make the system generality and expansibility greatly enhance."Furthermore, test items, processes and parameters can be easily and flexibly configured, and can be deployed quickly to meet the test requirements brought about by rapid product upgrading.
